Preopterećenje operatora<br />
• svi ugraĊeni aritmetiĉki operatori imaju svoje funkcije<br />
function r = plus(p,q)<br />
% POLYNOM/PLUS Implement p + q for polynoms.<br />
p = polynom(p); q = polynom(q);<br />
k = length(q.coef) – length(p.coef);<br />
r = polynom([zeros(1,k) p.coef] + [zeros(1,–k) q.coef]);<br />
end<br />
» q = p + 1<br />
q =<br />
x^3 – 2*x – 4<br />
» r = p*q<br />
r =<br />
x^6 – 4*x^4 – 9*x^3 + 4*x^2 + 18*x + 20<br />
